June 25th, 2016 brings us 61-days away from the National Park Service Centennial. In this edition of the #CentennialCountdown we go back 61-years to 1955 and the establishment of the Arlington House (Robert E. Lee Memorial), Cumberland Gap National Historic Park, Federal Hall National Memorial and Pu'uohonua O Honaunau National Historic Park.

The Robert E. Lee memorial was designated to honor Lee and his desire and hope that unity and peace would come to pass in our nation.

Westward travelers, buffalo, native americans, pioneers all traveled the gap through the Kentucky mountains to head west, this park commemorates that place with Cumberland Gap National Historic Park.
